The apparatus. of this invention is' to be associated with a conventional typewriter for driving the platen of the typewriter andfor driving a controlling. mechanism associated therewith to position the paper web carried through the typewriter by the platen in predetermined preselected positionshaving a predetermined sequence and to repeat the sequence upon a subsequent portion of the web." Referring to Figure 1, the typing machine platen control of this invention consists of a driving motor Hi 'connected'to a clutch mechanism II through means of a coupling 12. The

clutch II has a power output shaft l3 suitably" geared toa counter'shaft 16. A linespacing and sheet length control member I! is mounted upon the shaft I6 and has associated therewith a stop control i8 for regulating the degree of rotation of the line spacing and sheet lengthcontrol member l1. x

Theaforementioned mechanism is carried upon a frame consisting of a base member l9 having vertical side frames H. The side frames 2| extend in an upwardly direction on opposite sides of the base member l9 and are tied to therewith for driving the platen 36 of a typing Y machine-4U. v

The typing. machine 48 is of conventional'construction consisting of a frame 39 which carries the keyboard 4|. The frame 39 supports a' trans versely movable carriageAZ which in turn supports the platen 36. A'type ribbon is provided adjacent th-e'platen 35 in conventional manner and is supported by suitable spools; The usual spacingbar 45 is provided for manually rotating the platen tfi'while the paper release for the pressure rollers which retain the paper in engagement with the platen 36 is operated by means of a suitable and conventional lever in adapted the conventional manner. The end of the shaft 41 carrying the platen 36 is provided with knurled knobs 48 for manually rotating the platen 36 when desired.

Operation of the clutch 'II is controlled by means of the push buttons 50. 51Iand 52 for initiating actuation of the clutch mechanism to drive the platen operating'mechanism for rotating the platen for line spacing or for advancing or reversing the motion of the paper within the typing machine. The apparatus of this invention is particularly adaptablefor feeding a paper web consisting of a pluralityof individual webs in adjacent superimposed relationship through a typing machine for line spacing the web in the. machine at predetermined positions and. for repeating the identical line spacings as the webis passed through the machine so that typing can be accomplished upon repeated forms upon identical lines as the continuous web is fed through he machine. The carbon handlin device 25 for permitting the makingof a bluralinumber of. copies upon the individual webs; is: of the type wherein sheet carbcn is: used. When passing a continuous web of repeated forms through a typ ins machine and when using said-carbon f nduplicationof copies, itis necessary that; thepao rweb-and carbon shall be simultaneously fed; into the machine for-typingpurposcs. Aftenthctyping' has been completed upon. one of: the forms the paper web and. the carbon sheets must be backed out of the-machine; so that; the: carbon.

sheets will be engaged by suitable mechanism. of:

I86 for securing the flywheel to the clutch drive shaft 64.

The forward face of the flywheel I86 is provided with a boss I9I which has a finished surface thereon to engage a leather key I92 positioned within a slot I93 provided in a coupling member I94 journaled upon the motor shaft I90. The coupling member I94 is secured to the motor shaft I90 by means of the set screw I95.

The. face of the coupling member I94 is provided with a cylindrical recess I96 which is just slightly larger in diameter than the boss .I9I on the face. of the flywheel I86. A transverse rectangular recess l ljixrisv provided in the face of the coupling member l94 A rectangular leather key I92 is disposed within the recess and is provided 9 with ahole I91 through which the motor shaft IP9UTGX17BBQS.
